Abstract: PURPOSE: A dendropanax morbifera composition is provided to improve the curing rate of a dendropanax morbifera remarkably, due to the multiple hardening of sulfur coating of which a small amount of thermal initiator and photoinitiator are added, by heat and light spray. CONSTITUTION: A dendropanax morbifera composition comprises0.5-5wt% heat initiator and 0.5-5wt% light initiator on the basis of the total amount of paint composition. The heat initiator comprises 2,2'-azobis(2-methylpropionitrile). The light initiator comprises 2-hydroxy-2-methyl-1-phenyl-1- acetone. The weight ratio of the heat initiator and the light initiator added to the composition is 9:1-1:9.

Abstract: The present invention relates to a manufacturing method for an ultraviolet (UV) curing optically clear acrylic adhesive with an improved refractive index including a hafnium carboxyl group and, more specifically, to a manufacturing method for a UV curing optically clear acrylic adhesive with an improved refractive index including a hafnium carboxyl group that copolymerizes 2-ethylhexyl acrylate, 2-phenoxyethyl acrylate and acrylic acid, and hardens ingredients with UV by mixing the ingredients with hafnium carboxyl ethyl acrylate. The manufacturing method for a UV curing optically clear acrylic adhesive comprises: a step of copolymerizing 2-ethylhexyl acrylate, 2-phenoxyethyl acrylate and acrylic acid with ethyl acetate, which is a solvent, under a presence of catalysts; a step of manufacturing a mixture by mixing the copolymers with hafnium carboxyl ethyl acrylate; and a step of irradiating the mixture with UV.
